Overview of Toyota Tundra Gas Tank Size

Standard Toyota Tundra Gas Tank Size

The 2022 Toyota Tundra has a gas tank size of 22.5 or 32.3 gallons, depending on the trim level and model options. The 22.5-gallon gas tank size is standard on the SR, SR5, and Limited trims, while the 32.3-gallon gas tank size is standard on the Platinum and 1794 Edition trims.

Optional Toyota Tundra Gas Tank Size

In addition to the standard gas tank size, some Toyota Tundra models have an optional gas tank size. For example, the 2007 Toyota Tundra has a standard gas tank size of 26.4 gallons, but some models have an optional gas tank size of 37.5 gallons. The optional gas tank size is a good option for people who need to drive long distances without stopping for gas.

The optional gas tank size is not available on all Toyota Tundra models, so it's important to check the specifications of the specific model you are interested in.

Toyota Tundra Miles Per Gallon Ratings by Engine Size

Here is a breakdown of the number of miles per gallon a Toyota Tundra is capable of achieving based on the year and size of the engine.

Year Engine Size MPG (City/Highway)
2022 3.5L V6 14/18
2022 5.7L V8 13/17
2021 5.7L V8 13/17
2020 5.7L V8 13/17
2019 5.7L V8 13/17

Assuming you need the power and capacity of a full-size truck like the Toyota Tundra, those miles per gallon numbers sound fairly normal. Some trucks with a 6-cylinder engine can achieve up to 20 miles per gallon though they might also sacrifice over a ton of towing capacity. Most 8-cylinder powered trucks are within 1 or 2 miles per gallon of the Tundra.

Miles Per Gallon and Range

As you can see, the fuel efficiency of the Toyota Tundra has remained consistent in recent years. The 3.5L V6 engine gets better gas mileage than the 5.7L V8 engine. It is also important to consider the range of the Toyota Tundra. The range is determined by the fuel capacity and the fuel efficiency. The typical gas tank size for the Toyota Tundra is between 26.4 and 38 gallons, depending on the trim and configuration. With a combined MPG of 19, the Toyota Tundra can travel between 499 and 722 miles on a full tank of gas.

Factors Affecting Gas Tank Size of Toyota Tundra

Drivetrain Type

The drivetrain type also plays a role in the gas tank size of a Toyota Tundra. The gas tank size of the four-wheel-drive Tundra is slightly smaller than that of the two-wheel-drive models. The 2021 Toyota Tundra 4WD gas tank size ranges from 26.4 to 38 gallons, while the 2WD models have a gas tank size of 26.4 to 38 gallons.

Double Cab vs CrewMax

While the presence of a Double Cab in which the backseat is much smaller than the CrewMax cable which has room for three adults doesn’t have an immediate impact on the fuel tank size or the miles per gallon, there is one significant difference: the more weight you put in the backseat, the lesser fuel mileage you'll get. In other words, if you drive a Toyota Tundra double cab, you’ll probably burn less fuel just because you are likely to carry less weight in the interior.

Trim Level

The trim level of a Toyota Tundra can also impact the gas tank size. The higher the trim level, the larger the gas tank size. For example, the 2021 Toyota Tundra Platinum and 1794 Edition have a 38-gallon fuel tank, while the SR and SR5 trims have a 26.4-gallon fuel tank.

It is important to note that the miles per gallon and range of a Toyota Tundra can vary based on driving habits, terrain, and weather conditions. It is essential to maintain the vehicle properly to ensure optimal fuel efficiency and range. Sources: - -

How to Improve Fuel Efficiency

Driving Speeds

One of the easiest ways to improve fuel efficiency is to drive at a reasonable speed. According to the U.S. Department of Energy, fuel efficiency decreases rapidly at speeds above 50 mph. In fact, every 5 mph you drive above 50 mph is like paying an additional $0.18 per gallon of gas. Additionally, rapid acceleration and hard braking can decrease fuel efficiency by up to 33% on the highway and 5% in the city.

So, to improve your Toyota Tundra's fuel efficiency, try to maintain a steady speed and avoid sudden accelerations and hard braking. Not only will this save you money on gas, but it will also reduce wear and tear on your vehicle.

How Towing Weight Affects Gas Mileage

If you frequently tow heavy loads with your Toyota Tundra, it's important to understand how this affects your gas mileage. The weight of the load you're towing can have a significant impact on your vehicle's fuel efficiency. The more weight you're towing, the more fuel your vehicle will consume.

According to the U.S. Department of Energy, every 100 pounds of extra weight in your vehicle can decrease fuel efficiency by up to 2%. So, if you're towing a heavy load, try to remove any unnecessary items from your vehicle to reduce the weight.

Additionally, it's important to choose the right trailer for your towing needs. A trailer that's too heavy for your vehicle can significantly decrease your fuel efficiency. Be sure to check the towing capacity of your Toyota Tundra and choose a trailer that's within that limit.

Other Factors That Impact Fuel Efficiency

There are several other factors that can impact the fuel efficiency of your Toyota Tundra, including:

  • Driving style: Aggressive driving, rapid acceleration, and hard braking can decrease fuel efficiency.
  • Tire pressure: Underinflated tires can decrease fuel efficiency by up to 3%.
  • Vehicle maintenance: A poorly maintained vehicle can decrease fuel efficiency. Be sure to keep up with regular maintenance, such as oil changes and air filter replacements.
  • Fuel type: Using a higher-octane fuel than your vehicle requires will not improve fuel efficiency and can actually decrease it.

Using any of the above factors to make your pickup truck more efficient will help you visit the gas station a little less often. With gas prices hovering between $3 to $4 per gallon depending on where you live, that seems like welcome news to most anyone!
